Hi Guys,
I have one question that I would like all Sifus to give their valuable inputs. I currently have this problem which I don't have a clue on what the issue is.
Here it goes....
1) What should be the voltage reading at idling?
2) What should be the voltage reading when you switch on your air-con + head lamps?
3) Will the voltage drop when the air compressor kicks in?

My voltage is ~12+ v before I start my engine. After I start my engine, the voltage will increase to ~13 plus...
